an object which floats in water weighs 5N in air. a. what is the weight of the object in water? b.what is the upthrust acting on the object in water?c.what is the weight of the water displaced by the object? d. the density of water is 1g/cm 3. if an object with a mass of 100 g has a weight of 1 N on earth, calculate the volume of water displaced by the object.

Answer:
Here is your answer
Explanation:
Exactly the same. Weight, which is really a measure of Gravity acting on mass, is constant. If the object weighs 5 Newtons in Air, it still weight 5 newtons in water. It just so happens that water is a whole lot more dense than air and the water displaced was more than h 5 newtons worth, so it floats. If the object was a lot smaller (Denser) it would sink in water, but it’s weight would not change.
Conflating float vs sinking is a measure of (water) displacement which is conditioned on how much water was displaced, which is itself conditioned on the size of the object as well as its weight, weight being on Gravity, not size. The objects mass remains equal in either case.
